Summary
The sorption of milligram amounts of gold, palladium and silver on a chelating sorbent of pyrazolone type is studied. A fourfold increase in sorbent capacity towards the precious metals is recorded at 65°C, compared to room temperature. The developed procedure permits to separate milligram amounts of gold, palladium or silver from both microgram or milligram amounts of non-precious metals.
